RESUMO
Background: Thoracolumbar burst fractures (BFs) are traumatic lesions instigated by compression forces. Canal compression and compromise may lead to neurological deficits. Optimal surgical management is yet to be fully defined since various approaches such as anterior, posterior, or combined exist. This study aims to determine the operative performance of these three treatment modalities. Methods: In accordance with the PRISMA guidelines, a systematic review was performed, identifying studies comparing anterior, posterior, and/or combined surgical approaches in patients with thoracolumbar BFs. To analyze available evidence, a Bayesian network meta-analysis framework was utilized. Results: In this study, 16 studies were included. The shortest operative times and lowest operative blood losses were found for a posterior approach. The length of stay (LoS) was shorter with the posterior approach compared with the other two modalities. Return to work, postoperative kyphotic angle (PKA), and complications all favored the posterior approach. The visual analog scale score was similar between groups. Conclusions: This study suggests that the posterior approach has significant advantages in terms of operative time, blood loss, LoS, PKA, return to work, and complication rates when compared to the other approaches. Treatment should remain an individualized process, and before choosing an approach, factors such as patient characteristics, surgeon experience, and hospital settings should be considered.
RESUMO
Background: A thoracolumbar burst fracture (BF) is a severe type of compression fracture, which is the most common type of traumatic spine fractures. Generally, surgery is the preferred treatment, but whether the optimal approach is either an anterior or a posterior approach remains unclear. This study aims to determine whether either method provides an advantage. Methods: Following PRISMA guidelines, a systematic review was conducted, identifying studies comparing anterior versus posterior surgical approaches in patients with thoracolumbar BFs. Data were analyzed using Review Manager 5.3. Seven studies were included. Results: An operative time of 87.97 min (53.91, 122.03; p<0.0001) and blood loss of 497.04 mL (281.8, 712.28; p<0.0001) were lower in the posterior approach. Length of hospital stay, complications, reintervention rate, neurological outcomes, postoperative kyphotic angle, and costs were similar between both groups. Conclusions: Surgical intervention is usually selected to rehabilitate patients with BFs. The data obtained from this study suggest that a posterior approach represents a viable alternative to an anterior approach, with various advantages such as a shorter operative time and decreased bleeding.
